Autonomous cooperative control technology for frequency and oscillation of grid-forming energy storage
The decoupled control of primary frequency regulation characteristic and virtual damping characte-ristic for grid-forming energy storage is the key to realizing multi-objective comprehensive control of frequency support and oscillation suppression. The coupling mechanism and parameter design contradiction between the primary frequency regulation parameter and the virtual damping parameter of grid-forming energy sto-rage are analyzed,and the output characteristic model of virtual synchronous generator is established. The influence mechanism of factors such as the angular velocity of virtual synchronous generator,rotor damping and stator impedance on the output power is deeply analyzed,the decoupling design for the frequency and oscillation control parameters of virtual synchronous generator is conducted,and a multi-objective autonomous cooperative support control strategy for frequency and oscillation of grid-forming energy storage is proposed. A simulation system with a high penetration rate of wind power and energy storage is established to verify the effectiveness of autonomous and cooperative participation of grid-forming energy storage in system frequency support and oscillation suppression under the proposed control strategy.
